Hello,

I used Rad docking panel, in one of the panes I added a treeview, which at the time, the tree view's scrollbar shows up correctly when I expand items.

Then I also need to put in a button in that panel, so I put the treeview inside a stackpanel. after that, the treeview's scrollbar is gone.

I knew I did something wrong but couldn't figure out what. please help. Thanks.... Christina

Hi Chris,

If you want the ScrollBar of the RadTreeView to be visible, you have to put it in a Grid instead of a StackPanel. I am attaching a sample project which demonstrates a RadTreeView control with a visible ScrollBar.
